has anyone noticed a difference in the HIBERNATE or SUSPEND modes when you close the lid?
no matter what i choose, the laptop is still warm the next day.
i thought one of those was to put the laptop into a sleep like mode which basically turns everything off but not totally off.
and i just noticed (after a night) that the fan must have been running all night long too.
surely there must be a way to 'sleep' this laptop, or?

I have just install Ubuntu 11.10 64 bits on Samsung 900X today. At first, the computer was noisy and hot but after applying the fix of page 12, It have improved so much.The system is perfectly usable, almost everything works fine. However, there are things that could be improved/fixed:
-Touch-pad multi-touch and gestures: I have experience some problems with right click so I apply the psmouse fix. About multi-touch; I have realized that people had MULTITOUCH in previous versions (they activate some gestures in pref>mouse>touchpad). With 11.10 it's like the computer detects touchpad as a mouse so "Touchpad" window it's not showed. Does anybody have multitouch or ubuntu detects the hardware correctly?
-Keyboard Light Keys: they are off as default, the key don't work. I do some research and I don't found any working fix.
-Battery life: with the fix I said at first I have about 3 hour of battery power with wireless and max screen brightness .
I will keep trying to fix this problems, any collaboration is valued
Thank you for your attention and interest
Using Broadcom BCM43225 802.11/g/n (rev 01) in Debian testing on a 900X1B, both Open Source brcm80211 and closed sourced Broadcom STA driver perform poorly, losing around 25% of the packets just pinging the AP. The STA driver seems to be less prone to frequent disconnections.
None of the drivers support power saving (it is planned for brcm80211), you can make things better by turning off power save for the wireless interface. You can check the current configuration with
If your wireless interface (wlan0 for brcm80211, eth1 for STA) has a line like thisCode:sudo /sbin/iwconfig
the power management is on, otherwise you should seeCode:Power Managementmode:All packets received
The wireless power management can be turned off withCode:Power Management:off
As a simple test you can start pinging an AP with power management on and after a while turn off power management, you should see ping times drop by two orders of magnitude.Code:sudo /sbin/iwconfig power off
This change can be made permanent by creating the file
/etc/pm/power.d/wireless containing the two lines (use wlan0 instead of eth1 if you are using the brcm80211 driver):
The file must be executable, you can set the persmissions byCode:#!/bin/sh /sbin/iwconfig eth1 power off
SeeCode:sudo chmod +x /etc/pm/power.d/wireless
It is far from perfect, but with power management off the performance is acceptable.

Things were working ok with 11.04. After upgrading to 11.10, I've had weird wifi issues. I decided to do a clean install. It worked fine for a while, but not I have no wifi at all... Any help getting started with debugging this? Thanks!
It works great for me.
Just finished installing 11.10 on a brand new Samsung 900X3A-B02 (revision 2).
So far most of it works out-of-the-box: wifi, bluetooth, camera, mic, etc.
What doesn't (the usual suspects):
- fn+F7/F8 (keyboard dimming)
- fn+F1 (settings?)
- fn+F6 (power mode)
- fn+F12 (toggle wifi)
Other stuff that's missing:
- fn+F5 to toggle touchpad works, but an empty notification pops up.
- Touchpad is recognized as a mouse (not Touchpad tab in the settings, no multitouch settings
